Globular clusters are stable, tightly bound groups of tens of thousands to millions of stars that are associated with all types of galaxies. According to NASA, it is possible that globular star clusters once ruled the Milky Way. Back in the old days, back when our Galaxy first formed, perhaps thousands of globular clusters roamed our Galaxy. Today, there are less than 200 left.Today's NASA Astronomy Picture of the Day is the globular star cluster NGC 2419. It is a multi-generational star cluster located about 300,000…

Today's NASA Astronomy Picture of the Day is the Spiral Galaxy, also known as NGC 2841. It is an unbarred spiral galaxy located about 46 million light-years away in the constellation of Ursa Major, which is also known as the Great Bear. According to NASA, NGC 2841 has a relatively low star formation rate as of now, in comparison to other spirals that are alight with emission nebulae.The picture of NGC 2841, which spans about 150,000 light-years, was captured by astrophotographer Roberto Marinoni. About Spiral…

Galaxies exhibit an array of sizes, ranging from diminutive dwarf galaxies with a meager population of a few billion stars to colossal elliptical galaxies with trillions of stars. According to NASA, Spiral Galaxies have winding spiral arms that make them look a little like massive pinwheels. These disks of stars, gas, and dust have bright bulges in their centers made up primarily of older and dimmer stars. Their whirled arms are typically full of gas and dust, which helps give rise to the bright, younger stars visible…

Here is what NASA’s James Webb Space Telescope has snapped- NGC 346 star birthing region. Star formation is not only a mysterious process, but also an awe-inspiring occurrence. And now, NASA's James Webb Space Telescope has taken an image of the star forming region called NGC 346. The mission is to know more about the star formation process in the early universe. Notably, NGC 346 is one of the most dynamic star-forming regions in nearby galaxies and it is full of secrets. However, this James Webb Telescope image has…

The new findings from the James Webb Space Telescope is all about solving the mysteries of NGC346, one of the most dynamic star-forming regions in near our Milky Way Galaxy, says ESA. The universe is full of mysteries. Some are horrifying and some are awesome. To find out what is going on in outer space, NASA and ESA have deployed a number of telescopes and the newest one is the James Webb Space Telescope. Its biggest job is to look back in time to find out about the origin of our universe. The new findings from the…

It hasn't even been a fortnight since the first image release, and the James Webb Space Telescope is just continuously knocking all our socks off.Only a few images have been officially released, but that hasn't stopped citizen scientists digging through the raw data to see what they can find.  One of those is Judy Schmidt, who has been processing raw space data into breathtaking images for years. Courtesy of her painstaking work, we now have absolutely jaw-dropping images of two spectacular spiral galaxies.The first is…

Astronomers have observed in a relatively nearby galaxy a star that not only survived what ordinarily should have been certain death — a stellar explosion called a supernova — but emerged from it brighter than before the blast.Meet the 'zombie star'.The star at issue, observed with the Hubble Space Telescope, is a kind known as a white dwarf, an incredibly dense object with about the mass of the sun crammed into the size of Earth. A white dwarf is the remaining core of a star that blew off a lot of its material at the end…

By NASA's Goddard Space Flight Center June 24, 2022NGC 2392 is a bipolar double-shell planetary nebula.About 5,000 light-years from Earth, the stunning nebula NGC 2392 formed after the demise of a star like our Sun.In this sonification, the image is scanned clockwise like a radar. The radius is mapped to pitch, so light farther from the center is higher pitched. The outline of the nebula’s shell can be heard in the rising and falling of pitch, punctuated by its spokes. Brightness controls the…

By NASA's Goddard Space Flight Center June 19, 2022The majestic spiral galaxy NGC 1300’s arms hold blue clusters of young stars, pink clouds of star formation, and dark lanes of dust.To represent this image with sound, scientists assigned louder volumes to brighter light. Light farther from the center is pitched higher as a counterclockwise radar scans across the galaxy. NGC 1300 resides nearly 70 million light-years away in the constellation Eridanus.https://www.youtube.com/watch?v=t6K65osxVJUSonification credit: SYSTEM…
